jquery常用方法小结

1、日期格式处理与获取

 1 function setDate(){
 2        var mydate = new Date();
 3        var nowYear = mydate.getFullYear();
 4        var nowMonth = mydate.getMonth()+1;
 5        nowMonth=nowMonth>9?nowMonth:"0"+nowMonth;
 6        var lastYear=nowYear-1;
 7        var lastMonth=mydate.getMonth();
 8        lastMonth=lastMonth>9?lastMonth:"0"+lastMonth;
 9        $("#tjqq").text(nowYear+"-01");
10        $("#tjqz").text(nowYear+"-"+nowMonth);
11        $("#sqq").text(lastYear+"-01");
12        $("#sqz").text(lastYear+"-"+lastMonth);
13        //str += (mydate.getMonth()+1) + "月";
14        //str += mydate.getDate() + "日";
15        //return str;
16 }

2、字符串替换

1 var re=new RegExp("-","g");
2 var tjqq=‘2020-.1-01‘.replace(re,"");//20200101

3、获取一个数组的最大值/最小值

1 var arr=[10,20,30];
2 function largestOfFour(arr) {
3     var newArray = arr.join(",").split(",");
4     return Math.max.apply({}, newArray);
5 }
6 function minOfFour(arr) {
7     var newArray = arr.join(",").split(",");
8     return Math.min.apply({}, newArray);
9 }

4、数组去重

1 var arr=[10,20,20,30];
2 $.unique(arr)
